Problems solved by technology

The thermal insulation pipe sleeve of the above structure is usually made of glass fiber reinforced plastic material with built-in thermal insulation material. It has a certain hardness, but is brittle and easy to break, which affects its service life, and the glass fiber reinforced plastic material itself is easy to age; The resulting pipe sleeve is not beautiful in appearance, heavy in weight, and inconvenient to install and use, so it is not suitable for heat pipe insulation in nuclear power plants

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with accompanying drawing: figure 1 As shown, the present invention is composed of two halves of a semicircular cross section, the sleeve 1 is made of a stainless steel inner layer 2 and an outer layer 3 sealed, and the inside is vacuumed; the sleeve 1 is provided with There is a mesh body 5 composed of reinforcing ribs 4 .

[0016] figure 2 As shown, the mesh body 5 is composed of a set of transverse reinforcing ribs 51 and a set of vertical reinforcing ribs 52 arranged in a staggered manner. The reinforcing ribs 4 constituting the net-like body 5 are in contact with the inner walls of the upper and lower stainless steel inner layers 2 and stainless steel outer layers 3 respectively through the heat insulation pad 6 at the upper and lower ends; the sides of the stainless steel outer layer 3 or A vacuum point 7 is provided on the front side.

[0017] In other embodiments of the present invention,...

Abstract

The invention discloses a vacuum thermal insulation pipe casing which is at least composed of a dimidiate casing body of which the cross section is in hemicycle. The casing body is formed by sealing a stainless steel inner layer and a stainless steel outer layer and is vacuumed internally; a reticulate body composed of reinforcement fillets is arranged in the casing body; the reticulate body is at least formed by staggered arrangement of a group of transversely arranged reinforcement fillets and at least one group of vertically arranged reinforcement fillets; the side surface or the facade of the stainless steel outer layer is provided with vacuumizing points; the upper end and the lower end of the reinforcement fillet forming the reticulate body respectively contact with the inner walls of the upper stainless steel inner layer and the lower stainless steel outer layer via an insulating mat; the stainless steel outer layer is made of skidproof stainless steel plates; and the outer surface of the inner layer is provided with a plurality of toothed crossers contacting with the cased pipelines. The invention has the characteristics of simple structure, convenient installation and use, beautiful appearance and firm inner structure, can prevent stepping and is skidproof.

Description

technical field [0001] The invention relates to a pipe sleeve used for heat preservation of a thermal pipeline, in particular to a vacuum heat preservation pipe sleeve made of stainless steel. Background technique [0002] In the prior art, there are many insulation pipe sleeve products specially used for thermal pipelines, and a pipe sleeve composed of two halves of pipe sleeves with a built-in insulation material is the main one. Between the two pairs of half pipe sleeves Hasps are provided to connect the two pairs of half pipe sleeves to each other to form a complete pipe sleeve after they are sleeved on the heat pipe. The thermal insulation pipe sleeve of the above structure is usually made of glass fiber reinforced plastic material with built-in thermal insulation material. It has a certain hardness, but is brittle and easy to break, which affects its service life, and the glass fiber reinforced plastic material itself is easy to age; The resulting pipe sleeve has an u...
